With most other spark plugs, debris build-up tends to be a major issue. They have a platinum electrode in the center which consumes less power than the nickel alloy electrode of copper spark plugs. Silver-tipped spark plugs have the best thermal conductivity. The quality of the materials they’re made from are a huge factor in their longevity and power. In the center of the iridium spark plug, there is a small electrode which reduces the amount of voltage needed to generate an electric current. Around that rod is wrapped a ceramic insulator, and around that a metal case. It's more expensive than the regular copper plug. If it's an alloy, it would also be interesting to see its melting point (Iridium melts at ~ 2450°C while Platinum at ~ 1770°C and Silver at 960°C so if Ir/Ag is an alloy with low percent Ag, it could have an higher melting point with respect to Pt). It is even more durable than platinum. Of course, whenever you have a top-quality auto component like this, you can expect it to be more expensive. You must log in or register to reply here.

Denso makes plugs in the US (at least for the US aftermarket) not sure about other global markets. Unlike conventional spark plugs, where the discharge is constrained by the ground electrode, Brisk Premium Spark Plugs utilize a design where the ground electrode is retracted so the spark discharge occurs at the very tip of the spark plug. Take a look at post #30 of. With the design of a fine wire center electrode, iridium spark plugs conduct the better electrical energy and boost firing efficiency. kescott1910. Answer: Because the thermal conductivity of silver is so much better than that of any other metal, the physical appearance of Nology Silver spark plugs … Bosch Silver Spark Plugs are engineered for older European performance cars by using silver alloys in the center electrode tip to resist wear & improve spark plug efficiency.
